| Abstract: | The effects of second jet pressure, spinning speed and condenser width on the structure and properties of polyester-viscose blended jet-spun yarn have been studied. Tracer fibre technique has been used for the structural analysis of the yarn and the yarn properties such as tenacity, CSP, flexural rigidity, hairiness, unevenness and imperfections have been determined and explained in the light of structural parameters. Increase in wraps/mm has been observed with the increase in both jet pressure and Spinning speed. Increase in jet pressure increases yarn tenacity and flexural rigidity but decreases yarn hairiness. Maximum yarn tenacity is obtained at 180m/min spinning speed and at comparatively high second jet pressure(4 kg/cm2). Increase in spinning speed increases U%, imperfections and hairiness. |
